Canon EF to M43 Speedbooster on the horizon

It’s look as if Metabones will release a new adaptor in August that will allow your micro 4/3 cameras to adopt Canon EF via an electronic speedbooster.

If you’re like myself who is a Canon shooter with a large EF lens collection, this is fantastic news. The Blackmagic Pocket Cinema Camera, Panasonic GH2, GH3 will now electronically except EF mount lenses, whilst increasing the sensor’s field of view, added sharpness and light sensitivity.

Canon EF lenses use proprietary electronics to control the aperture, IS and AF; this complicates full compatibility with other camera bodies via adaptors; It’s the reason why Camera “X” to EF mount always takes a little longer, and costs a little more.

For those who haven’t kept up to date on the fantastic invention of the speedbooster, this adaptor increases your field of view by 0.71x, increases the sharpness of your lens, and increases light sensitivity by 1 stop.

Please note, this only works with active m43 mount cameras, therefore will not work with The Blackmagic Cinema Camera MFT (unless your EF mount lenses are manual aperture).

However, it will be a great addition to the Blackmagic Pocket Cinema Camera and will turn your 50mm f/1.4 lens into a 102mm f/1.0! This adaptor makes the pocket cinema much more appealable now, especially if the adaptor powers the IS (Image Stabilization) like the Canon EF to Sony E mount does.
